Smaller versions, like the cuirass ventilator and jacket ventilator, enclose only the patient's torso. Breathing in humans occurs through negative pressure, where the rib cage expands and the diaphragm contracts, causing air to flow in and out of the lungs. The concept of external negative pressure ventilation was introduced by John Mayow in
The jacket ventilator, also known as a poncho or raincoat ventilator, is a lighter version of the iron lung or the cuirass ventilator, constructed of an airtight material (such as plastic or rubber) arranged over a light metal or plastic frame, or screen, and depressurized and repressurized by a portable ventilator.

An open-source ventilator is a disaster-situation ventilator made using a freely-licensed design, and ideally, freely-available components and parts. Designs, components, and parts may be anywhere from completely reverse-engineered to completely new creations, components may be adaptations of various inexpensive existing products, and special ...
Mechanical ventilation helps move air into and out of the lungs, with the main goal of helping the delivery of oxygen and removal of carbon dioxide. Mechanical ventilation is used for many reasons, including to protect the airway due to mechanical or neurologic cause, to ensure adequate oxygenation, or to remove excess carbon dioxide from the ...
Spring Cleaning in an Infant Star System; Image title: This image depicts the dusty disc encircling the young, isolated star HD 169142. The Atacama Large Millimeter/submillimeter Array (ALMA) imaged this disc in high resolution by picking up faint signals from its constituent millimetre-sized dust grains.
Bubble CPAP is a non-invasive ventilation strategy for newborns with infant respiratory distress syndrome (IRDS). It is one of the methods by which continuous positive airway pressure (CPAP) is delivered to a spontaneously breathing newborn to maintain lung volumes during expiration.
An open source ventilator is a disaster-situation ventilator made using a freely licensed (open-source) design, and ideally, freely available components and parts (open source hardware).
Bag valve mask. Part 1 is the flexible mask to seal over the patients face, part 2 has a filter and valve to prevent backflow into the bag (prevents patient deprivation and bag contamination) and part 3 is the soft bag element which is squeezed to expel air to the patient
